I am new to Mtb still. Currently I am riding a Trek Mamba, but am looking to switch to a full suspension. Needless to say, there is a local man selling his 2008 Felt Compulsion 3. Has Rockshox front suspension and a fox rear. He is asking 750 for it. After a little research ive found the bike was 1900 brand new in 2008. Any ideas? All advice will be greatly appreciated.
